Question

A gas in a rigid container is heated so that its Kelvin temperature doubles. What happens to its pressure?
Select one:
a. Nothing
b. It doubles
c. It quadruples
d. It is halved

Answer 1

\[PV= nRT \]since the q is about pressure, lets make P as subject of this formula
\[P = \frac{ nRT }{ V }\]
so the gas was heated till T became 2T
\[P = \frac{ nR2T }{ V }\]

Answer 2

which means upper part of the fraction is doubled
while lower part is same as was
so what do you think will happen to pressure?

Answer 3

i think b ??

Answer 4

bingo!

Answer 5

thanks you @somy

Answer 6

no problem )
